UAZ PATRIOT Operation Manual page 138

long-term motor vehicle operation with disabled power steering
can lead to the premature wear of the steering system.
The total play of the steering system is inspected while the
engine is idling and the front wheels are positioned straight;
the steering wheel should be swung to both sides until the front
wheels turn. The total play cannot exceed 20°.
If the backlash is higher than the permissible level, detect
the unit which gives the increased play. Therefore the following
should be checked: proper tightening (see Annex 2) of the steering
box bolts, the tie rod joints, tightening of the propeller shaft
joints, air gaps in the joints and spline coupling of the steering
column propeller shaft, air gaps in the steering mechanism.
Tie rod joints do not require adjustment and lubrication
during vehicle operation. If non-repairable joints have an air
gap, replace them.
If a radial air gap in the joint of the steering shaft is detected
(axial displacement of the crosspiece in bearings) punch the
bearings in yoke eyes, so that the bearing sleeve is not deformed.
Replace the steering column propeller shaft if air gaps in the
spline couplings are detected.
If air gaps in the steering mechanism are detected, adjust the
mechanism at UAZ service station.
Tension of power steering pump drive belt see section "Engine
cooling system".
Replace the belt if damages or excessive stretch are
detected.
